保山市饮用水水源地水中的大肠杆菌分析

Analysis of Coliforms in the Drinking Water Sources in Baoshan City

对云南省保山市13个乡镇48个饮用水水源地水样中的总大肠菌群、耐热大肠菌群、大肠埃希氏菌的数量进行了测定,结果显示,同一乡镇不同水源地水样中的总大肠菌群数量差异较大,但不同乡镇间(以乡镇为单元)水源地水样中的总大肠菌群数量并无统计学差异,同时水样中总大肠菌群、耐热大肠菌群、大肠埃希氏菌的数量存在显著正相关。

In this study,we sampled 48 drinking water sources in 13 villages and towns in Baoshan City,a typical mountainous city in China,and compared the total coliform colony,heat-resistant coliform and Escherichia coli in the water samples.The results showed that the number of coliforms in different water sources of the same township was quite different,but there was no statistical difference in the number of coliforms in water sources between different townships(townships as a unit);and the number of different coliforms in water samples was significantly positive correlated.
